The Wielkopolski National Park is the area of tourism and recreation for residents of Poznań and surroundings therefore the bioclimatic conditions are to be of a great interest and the aim of the study. Daily measurements of temperature, humidity and wind speed at 12 UTC from the period 2002-2009 taken at the automatic station of the Ecological Station of Adam Mickiewicz University in Jeziory were used. The following indices were analysed: an equivalent temperature (Te), an effective temperature (TE), an air enthalpy (i) and a cooling value (H). These indicators were calculated using BioKlima 2.6 program. The bioclimatic conditions of the WPN are conductive to practicing if tourism and recreation. In the period 2002-2009 the area was characterized mare frequently by values of giving a feeling of comfort. The most comfortable bioclimatic conditions were noticeable from May to September, with a small decrease in summer (caused by the increase in number of hot and sultry days). High frequency of the thermal feeling from the class "cold" is beneficial for the area of practicing all kinds of physical outdoor activity.
